To all whom itn'tay concern? Be it known that I,RoBnR'rL,FRINK, citi= zen-e of the United States, resident of Cleveland, county of Cuyahoga, and 1 State T of. Ohio, have'invented a new nd'juseful'Imi evering Glass. of which the following is a speciprovement in Devices for Cylinders, fication, the principle ofthe invention being herein explained and the best mode in which- I have contemplated applying that principle, so as to distinguish it" from other inven tlons.

. States LettersiPatent' No. 846,l0 2, issued to me March 5, 1907. The feature of such My presentinvention, relating," as stated,

to devices for severing glass c'ylinder'sfha's particular regard to the. provision o f a de-. vice of this character for use in connection with glass drawing apparatus or mechanism of the kind described and claimed in United mechanism or apparatus, andjof the method therein involved, is the drawing of a con-- tinuous cylinder of glass of indefinite'len gth from a molten bath, sucll cylinder-not being cappedas is the case in prevailing methods of glass drawing. Obviously the conditions presented where the cylinder is thus drawn,

instead of being drawn in a single capped section of limited length, make possiblethe utilization of much more effective and in effect substantially automatic means for-severingfrom the continuous cylinder successive sections ofthe required length. It is'not intended, however, by thus referring my present invention to the specific glass drawing apparatusnoted above,ft o imply that The annexed drawings and the following,-

description set forthin detail certain mech anismembodying the invention, suchdis-- closed jmeans constituting, however, but one of various mechanical forms in which the principle of the invention may be used.,

Upon the platform" thus prov-ided'adjacent to the. opening'a-isf mounted the post or column B that c nstitutes the device-now to be upper-portion of this column is rotatably mounted a} sleeve-B that bears two-op central support of-the sever ng described. Upon the.

respectively, to extend over the opening a when properly. directed with reference to the-axis about which 'theyare'thus seen to thus direct thernis obviously effected by. r0

"tation of sleeve-B, and to facilitate such movement of the latter, handles 'b.are pr1b-, vidednear the lower end. thereof. In view,

of. the fact that all theweight of the apparati1s\is borne by this sleeve it is desir-' able that: the latter be formed with ballbearingor similar anti-friction means at'i-ts,

This cord 0 is attached to an eye in the upper end of a shaft, D to which the 'casing is attached by a head or cap that closes its upper end, Fig. 2. -The further function subserved by shaft D will appear "5 later. The casing is designed to be actu-' ated downwardly and to be normally maintained in lowermost position, by means of two rolls 0 in arm B having frichon engagement therewith, Fig.1. These rolls are borne upon suitable'sh'afts e the outer ends of which on one side are journaled in togglearms a, by proper actuation. of which latter the rolls can bethrown into and out of-engagement with the casing as desired. Rotation of the rolls, and consequent downwa'r ,act'uation of the casing when such. ioll f are in engagement therewith, is bad ,by ineansof-a small motor C mounted on a bracket b on one side by arm B and provided with a pinion 0 meshing with gears c on the correspondingouter ends of rollerbearing shafts '0 Fig. The electric-circuit wherein motor C is. included is controlled by means of a switch 6 conveniently mounted in rotatable sleeve'B adjacent to handles 5. t r

-Undue acceleration of movement on the partof easing C, when left free tomove upwardly, is prevented by a dash-pot arrangement shown in detail in Fig. 5. Such arrangement includes the provision of a vertical cylindrical chamber Z) in theouter end of 211111.13 in which cylinderis'reciprocable a piston c borne by a rod c 'that is adjustably mounted in a bracket G attached to the easing (1- Oneormore' grooves b two are shown, in the walls of cylinder 6'', such grohvesbeing of gradually.decreasingdepth to allow the piston and easing C'to which it is attached to n'iove rapidly at first but slow 7 up and-cushion the movement at the end; A. vent valve 5 in the closed end of the cylinder admits of'still further regulation of.

a such movement; Gentrally-suppu'rted withrfisuitable bear- I charge t ings in the upper end of easing C is the shaft already referred to, the lower end of which projects beyond the lower end of the casing. Upon the upper end of shaft 1) is n'utmnted a-pulley- (Z about which passes several times an actuating cord (.Z.

latter extend on of arm B into: position to be grasped by the operator in handles ,r Figs. 1 and Obviously, pullmg upon one of these handles ct wlll rotate the 'shaft;- in one direction, while pulling upon the other will rotate the same in the opposite direction. Upon the lower end of shaft D is fixedly mounted a. cross arm (Z having elongated slots in its respective outer portionsin which areslidably and also pivotally secured lever arms (Z The inner ends of such lever arms (li are secured to a ring rotatably mounted upon the lower end .of a tubular shaft E between collars'e'. The :weight of tubular shaft E is designedto be sufiicient, when the latter is left to itself, 'to actuate lever arms (l outwardly, and there by press their lower ends against the inside of the glass cylinder where the device as a 1 Whole is' in operative position with respect to the latter. The outer ends of such lever arms (1 are respectively provided with a roller (Z anda glass cutter (Z5, the latter being preferably of the rotary character shown. In order that rollerd" and cutter (Z may thus bear against the-inner surface of the cylinder at the proper angle, in case the device be employed with cylinders having different diametersflhe two elements in question are not mounted directly upon the lever arms in' question but upon short swiveled erztexisions d thereof, Fig. 2. 'By

:nese, adpistinent 1n the particular means, 0:. noted may be readily effected." 4 l Norm ally, for obvious reasons, lev'e'r arms zl require to be maintained in retracted p0- sition, the cutting operation taking place only in teryals. To hold tubular actuating shaft E in its upper position, corresponding to this inactive condition of the glass cutting device, a cord 6 haying a bi-..

furcated inner end is attached at such end to I the upper end of the tube E and at its outer end to a hand lever E mounted on sleeve B and adapted to be locked or clamped, in a manner readily understood and hence not shown in detail, to thus retain said tube. Cord eis suitably guided over pulleys b and 0 on arm B and the upper end 0 of easing C, respectively' Without tubular shaft E, wherewith the inner ends of leverarms al aslhas been 1 shown, are connected, is mounted a secondtubular shaft F- like'wise reciproeable with respeot'to the central supporting shaft D.

To, this shaft F are" pivotally secured the inner ends of. i';wo pairaof lever armsief that The p.139 device, being provided with are further of a weight F with which such tube is connected through a cord is suitably guided over pulleys Z2 b 611 arm B and standard I), and it'sinner end is bifurcated and an equalizer bar f interposed as in the case of cord 6. Weight F is mounted upon a rod f slidably held in vertically alined brackets Z2 projecting from sleeve B, and is designedto be retained inactive by a lever f mounted on the upper of said brackets and having a cam face disposed to engage rod 4 against movement as will be readily understood.

Certain accessory features, or details, including means for automatically releasing Fig. 1. Cford f lever f and for similarly controlling toggleject through opening a in platform A, and

' st-itutes the lower ed hook or latch 0 arm 6: and thus the engagement of friction rollersr with casing C, can, it is thought, be most readily described in connection with the operation of the'parts whose structure has now been set forth. Assuming then the upper end of a glass cylinderi G to just profurther assuming casing O with the mechanism borne thereby to be in its raised position but centrally'disposed over such opening, motorC will be set in operation and the feed rolls a, being thus actuated, will lower the casing to meet the oncoming cylinder. When ter will be maintained in such position, despite weight 0,

because of the continueden- 0 therewith. The cylin- 1.- Disposed in the path of the cylinder as it thus ascends is a stop plate 9 that conend or foot of a jointed vertically reciprocable rod G, Figs. 1 and 4. The lower portion of such rod is supported in a suitable .bearing in the outer ,end' of the bracket C attached to the adjacentportion of casing C while its upper portion 1s ada ted to release 'a spring-pressed lever 0 ii'o'm engagement by a pivotally.mount The effect of'this release is to cause the rolls 0 out of engagement with casing C,

I thus leaving the latter free to be drawn up- Wardly by weightc. .lFrom' the construction oi theupper section'of rod G and the piv- 'otal'f character of its connection. withllg e without the casing a sufficient this same stop-plate g and clamp the same the limit. of such downward movement of the. casing is reached the la't retract-idn of friction ;my' invention may gards the mechanism lower portion thereof, itwill be apparent that the' further upward movement of the rod,-once it has released latch 0 is not impeded by such latch, return movement, upon the lowering ofcasing C, interfered with. The latch and lever a, engaging therewith, are designed to be manually reset, or restored to their initial positions after rod G' has thus been returned to its lowerposition. Lever), before described as f, and.thereby weight F has its outer end disposed in the path of movement of the latter is adapted to effect the release of the weight in question with resultant actuation of gripping arms f.

- The'construction of such lever arm f, as in the case of latch device 0 is such as not to interfere with the return movement of stop 9.

Release of weight F, and retraction of friction rolls 0%,

are timed so as to occur in being designed to lock rod' against movement,

nor. is-its subsequent whereby upward the order here named, so that casing C is not 7 drawn upwardly until after the" cylinder gripping mechanism has become. eflect-ive. The immediate result of the two movements in question is to attach the severing mechanism as it were to the upwardly advancing cylinder so as to move in unisontherewith. The next operative step consists in releasing hand lever E and thereby 'to bring the glass-cutter, proper, into contact with the pulling down upon the cylinder. Upon now appropriate handle (P, such cutter is rotated once around within. the cylinder and the latter thereby neatly severed. Ordinarily the severed sect-ion will'at once part from the main portion of the cylinder along the line of the cut, owing to the'additional pull to which the former is subjected; if not a slight 1 tap upon the cylinder at such line will effect the desired result. Immediately the severed section is thus detached the'fwelght 0 is obviously entirely free, save for the braking action of the dash-pot,- to raise such section.

clear of'the cylinder below. The sleeve B" is now swung about through a half turn. so

as to position in turn the other arm-B over opening a, andv the corresponding severing mechanism is. lowered into the advancing cylinder as before, from which in due season a second section is severed.' Inthe meantime the first section is freed from the gripping device and lowered onto a suitable truck (not shown) positioned therebelow, andis thence removed to be" split and .flattened'. 'Theseveral parts of the mechanism having been 'reset and placed in order the device-is ready to be swung around'again so soon as the second-section has been cut off.
